Using Creator API access tokens in deluge script

Using Creator API access tokens in deluge script

I am working on generating download urls for files that are uploaded via a creator form.  I want to include these urls in record templates so they can be easily accessed.  The goal is to make downloading multiple attachments in a record as quick and easy as possible. 

I have:
1) used the zoho api console to get a client id and client secret for my application. 
2) I have also setup a Zoho OAuth connection in the Creator microservices.  
3) Successfully used the client id and client secret to receive the access code, and exchange it for an access token and refresh token.

Here is where I am stuck.  I am attempting to use this token to request a download from the creator api with the documentation here: https://www.zoho.com/creator/help/api/v2.1/download-file.html.  When I try to execute, the response for the invoke url appears to be encoded.  Is this formatted correctly?  Should this trigger the download on execution?  Thank you for taking a look.

void openAOAform()
{
id = 4367411000004666557;
idString = id.toString();
header = Map();
header.put("Authorization","Zoho-oauthtoken 1000.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
//info header;
response = invokeurl
[
url :url
type :GET
headers:header
connection:"zoho_oauth_connection"
];
info response;
}
